I've only just got GTAIV for PC and i decided to do some clothing skins for Niko. I Changed the jacket to black leather with a white/grey sweater underneath with a blue t-shirt under that. I replaced the jean design with some cool pair of dark blue police jeans with white trim.

I found a cool trainer that allows you to change almost everything. Including a clothing selector. The backpack looks cool as an accessory, i might find the file for it and change the colour so it looks even better with the outfit.
